Diagnostic Test

CHECK FOR CAN BUS DTCS
1. With the scan tool, check for CAN BUS DTCs.
  Are there any CAN BUS DTCs present?
  
  Yes
  - Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Diagnosis and Testing and perform the appropriate diagnostic procedure.
  - Perform CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
  No
  - Go to step 2
CHECK IF CONTROLLER WAS REPLACED
Has the Transmission Control Module been recently replaced?

Yes
- Go to step 3
No
- Go to step 5
CHECK IF CONTROLLER WAS PROGRAMED
Was the Transmission Control Module flashed?

Yes

No
- Flash the control module with the proper part number for the vehicle.
- Perform the CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
CHECK FOR OTHER DTCS
1. With the scan tool, check Transmission DTCs.
  Are the DTCs P0602 and U140F Active and P161B and P1729 Stored?
  
  Yes
  - Check the Controller part number coincides with the vehicle setup such as engine size. This is an indication of an improper vehicle configuration. Verify all configurations to the Vehicle Identification Number (VIN) and reprogram as necessary.
  - Perform the CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .

  - Go to step 5
CHECK THE TIPM FOR PROPER PROGRAMING OF TIRE SIZE
1. With the scan tool, check the TIPM for proper tire size programing.
  Is the tire size properly programed in the TIPM?
  
  Yes
  - Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for any Service Bulletins for possible causes that may apply. If no problems are found, replace the TCM in accordance with the Service Information.
  - Perform the CVT VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure .
